Athearn HO Heavyweight Diner / Coach / Observation, ATSF #1 (3) Overview

The so-called “heavyweight” passenger cars were introduced by Pullman in 1907 and had gained widespread acceptance by railroads in the 1910s. The use of steel as the primary car building material not only increased the strength and longevity of the cars, but also reduced the risk of fires from the wood and coal-burning stoves of the era. Even after newer cars were introduced, many of the heavyweight cars survived into the 60s and 70s on secondary runs or in MOW service.
